NAME
ARMServer - disk array server daemon.
SYNOPSIS
/opt/hparray/bin
DESCRIPTION
ARMServer is the server portion of the HP Advanced Disk Array management software. It monitors the
operation and performance of the disk array, and services external requests from clients executing disk
array commands. ARMServer monitors disk array performance and status, maintains disk array logs,
initiates diagnostics, and allows clients to examine and change disk array configuration.
ARMServer must be running to allow management of the disk array using the command line utilities.
Host I/Os are not dependent on
ARMServer and are serviced regardless of whether it is running or not.
Because of its importance in managing the disk arrays,
ARMserver is launched automatically when the
system is booted.
One of the most important functions provided by
ARMServer is retrieving and storing performance and
status information from the disk array logs. If
ARMServer is not running, the disk array will continue to
log data, but when the array logs are full older entries will be lost to make room for new entries. A "Log
Full" warning will be displayed if this condition occurs, alerting you to the fact that
ARMServer is not
running.
DIAGNOSTICS
All significant changes in disk array status detected by
ARMServer are entered in
/var/adm/syslog/syslog.log
. These entries form a history of disk array operation and can be
used to track operation.
DEPENDENCIES
The
arraymond disk array monitor requires ARMServer to be running to check the status of the disk
array. arraymond uses the arraydsp utility to retrieve status information about the disk array at reg-
ular intervals. When performing maintenance on the disk array (for example, downloading new firmware
code), arraymond can be turned off to avoid error messages generated because the disk array is not
accessible. To turn off arraymond and ARMServer use the following command line:
/sbin/init.d/hparray stop
To restart arraymond and ARMServer use the following command line:
/sbin/init.d/hparray start
VIRTUALVAULT SECURITY INFORMATION
Security Configuration

Privileges
The command has been modified to support least privilege. The potential privileges possessed by the com-
mand and their uses include:
allowdacread This privilege is raised to provide discretionary read access to the devices.
allowdacwrite This privilege is raised to provide discretionary write access to the devices.
allowmacread This privilege is raised to provide mandatory read access to the devices.
allowmacwrite This privilege is raised to provide mandatory write access to the devices.
filesysops This privilege is raised to allow the mknod(2) system call to succeed.
writeaudit The command generates its own audit records and submits these directly to the sys-
tem audit trail. This privilege is raised whenever the command needs to write an
audit record.
